Maybe Paul Allen was confused with someone else too. Seems a pretty clear story in the end. I believe that Bateman is a proposed schizophrenic and being that the story follows according to his perspective, there is the possible mental projection of the crimes.
All of the central characters are male, and many of Bateman's victims are female. When an acquaintance unexpectedly comes in and inquires about the stains, Bateman nervously claims they're "cranberry… cran-apple…" but they sure look bloody.
All of these events can be explained as happening inside Bateman's mind rather than in real life. See imdb. That is where he leaves the bodies of his victims. Did the murders really happen, or did Bateman just imagine it all? By 1997, Cronenberg was out and Mary Harron was in as director of American Psycho , according to a report from Variety at the time. This occurs several times in the movie and in the book, to intentionally make the viewer and the reader question the integrity of the narrator and his sanity.
What would that look like?
In the very next scene , we see Bateman aggressively arguing with some non-English-speaking dry cleaners about not bleaching what appear to be bloody sheets. But I took from it that making the film more ambiguous was the director's intent but that he failed to do so.
All rights reserved. Much of the discussion regarding the possibility of everything being in his mind focuses on the sequence which begins when the ATM asks him to feed it a stray cat.
But c'mon man, you had one fatal flaw.
But at some point, we're starting to see things through Patrick's eyes. While it's easier to imagine someone like Bateman getting away with murdering random homeless people, prostitutes, or women he meets while walking home, it's highly unlikely he's remained off the NYPD's radar with upwards of 40 murders.
Does he commit murders as someone else and get confused as to which are fantasies and which are real?
